NEW YORK (AP) — Mahmoud Khalil, a former Columbia University graduate student fighting deportation, is contesting Judge Emil Bove’s involvement in his appeal, arguing that Bove's past position as a senior official at the Justice Department, specifically overseeing investigations of student activists, presents a conflict of interest. Khalil, known for his pro-Palestinian activism, has been under scrutiny since the Trump administration began aggressive enforcement actions against dissenting noncitizens.

During a recent request, Khalil’s attorneys insisted that the entire panel, minus Bove, from the 3rd Circuit Court of Appeals review the case following a January ruling edging the government closer to executing the deportation. They cited Bove’s directive role in immigration enforcement against protests at educational institutions, which they argue creates an appearance of bias.

Bove, who has served on the federal bench since September, had previously represented Donald Trump in legal matters. The Justice Department, while currently representing the government in Khalil’s appeal, has expressed that they see no grounds for Bove's recusal but will defer to his discretion.

Khalil, who has legal permanent residency, was the first detainee revealed during the Trump administration's crackdown on activists critical of Israel’s actions. He is married to an American citizen, and together they have a young son, whom he missed the birth of while detained in a Louisiana immigration facility for three months.

Allegations against Khalil included accusations of association with Hamas, for which the Trump administration has failed to provide substantial evidence. He has responded, labeling these claims as unfounded and indicative of retaliative measures against his activism."
